When I go food court, fast food restaurant or any place for meal, beside hoping to get a seat, I also hope that the table and surround is not in a mess. Some people can eat till whole table super messy with bones, tissues etc scattered across whole table and even dropped them on floor. Don't think anyone (or at least most of us) will like the sight of it.
So I also don't create mess for others. If there a collection point nearby, just bring it over or to the nearest cleaner. Or at least clear any mess or stack plates/bowls properly.
btw, previously there a thread on this topic? Still remember that phase of *A relative told me: "don't do that, you are depriving old uncles and aunties work."*
Something similar, one of friend jokingly said "Don't litter then cleaner nothing to do" ....
